Shewhart X-Bar Chart

Description:Given a matrix, XCHART generates five variables that describe the parameters of a Shewhart X-bar chart for quality control purposes. Two limits, upper and lower, are determined, set 3 deviations from the mean, set the boundaries in which a process can vary and still allow the process to be in control.

I try to use this program but it open up with a menu requesting "mat:" I assume it is asking for the matrix number for example 6x6 but it doesn't matter what you enter it keeps on giving a bad argument type error. Please assist.
